Bug ID: 171474
Summary: [JSC] LabelScopePtr is not necessary
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org
Reporter: utatane.tea at gmail.com
At the time of introducing LabelScopePtr, there is code that copying m_labelScope. So, m_labelScope is Vector<> instead of SegmentedVector and a bit special handle (LabelScopePtr) is needed.
But right now, there is no code copying m_labelScopes. So, we can take the same design to Label, RegisterID etc. Use SegmentedVector and usual Ref<> / RefPtr<>. Then drops LabelScopePtr.
And we also makes LabelScope noncopyable.
